I have two very reputable Mustang performance shops near me and I'd like to develop a good relationship with them. I got a quote for a JLT cai for my 2014 GT. It's upwards of around $1200. Looking at itemized, it make sense, but its still kinds steep for what it is. The service I'm questioning is the DYNO tune @ $400. I'm a class B mechanic so I can easily do the install and figure out the tuner(I'll ask that in another thread), but do I really need to get it on a DYNO?

You can get an email tune instead. Make sure you have nice open roads to data log. The nice thing about a Dyno is you can do your pulls in a controlled environment.

It will cost some money though to get a device so you can get a new tune on your car, however there are cold air intake/tuner bundles on many mustang shop websites for like ~800 or so. That should include the price of at least one custom tune.

A dyno tune for a CAI is pointless.

If you go to a reputable online mustang speed shop like Lund, Brenspeed or American muscle, to name a few, you can get the CAI and Tuner for about $675 to $775 that comes with a tune intended for use with your car and with the CAI. Save the Dyno tuning for when you have a real upgrade that requires one like forced induction or head work.

I doubt you will notice the difference between the canned tune on the tuner and the Dyno tune for a CAI.

By the way, your 2014 already has a CAI. Most aftermarket that are open element style systems (including the JLT) are actually worse than your stock intake because they suck in the air from your hot engine bay instead of the fender well. The vast majority of power gain is from the tune.

The only reason to go with a cai on your car is for purely aesthetic reasons. There is no HP to be gained with an aftermarket.
